The invention relates to the field of cranes, and discloses a counterweight device and a crane wherein the counterweight device (100) comprises a support mechanism (110) for being mounted on a turntable (200) of the crane and extending to the rear of the turntable (200), a mounting mechanism (120) for mounting a counterweight (300), and a lifting mechanism (130) for connecting the mounting mechanism (120) to the lower part of the support mechanism (110), the lifting mechanism (130) comprises a lifting unit (131) for lifting the mounting mechanism (120). The torque of the counterweight can be increased by connecting the mounting mechanism for mounting the counterweight to the support mechanism extending to the rear of the turntable. And moreover, the mounting mechanism is connected below the supporting mechanism, so that the counterweight is prevented from being lifted to the height above the rotary table during disassembly and assembly, and the disassembly and assembly difficulty is reduced.
本发明涉及起重机领域,公开了一种配重装置和起重机,其中,所述配重装置(100)包括用于安装在起重机的转台(200)上并向所述转台(200)后方延伸的支撑机构(110)、用于安装配重(300)的安装机构(120)以及用于将所述安装机构(120)连接于所述支撑机构(110)下方的提升机构(130),所述提升机构(130)包括用于提升所述安装机构(120)的提升单元(131)。通过将用于安装配重的安装机构连接到向转台后方延伸的支撑机构,可以增加配重的力矩。并且,通过将安装机构连接在支撑机构下方,避免了拆装时将配重提升到转台上方的高度,降低了拆装难度。
